A series of tests were made to evaluate the thermal effectiveness of variable volume dry diving suits equipped with a NASA Project Apollo urine collection device compared to SDV wet suits. Six-hour dives at water temperatures from 35 F were successfully completed with no apparent problems except cold feet. Breathing gas consumption, oxygen consumption, and carbon dioxide production were measured during the dives which included rest, and intermittent light and moderate exercise. A rewarm technique involving the circulation of hot water around the torso area in a rewarm garment was evaluated using subjects and in microchronic and acute hypothermia. The method was found to produce a rapid return to thermal equilibrium with a small rectal temperature afterdrop. Author
